Stone knowledge: the safety of artificial stone
People in home decoration are very concerned about the "radioactivity, radiation" of stone. Is the radioactivity of the stone strong? How can we choose the safe stone? Wuhan Fuhai Property Service Co., Ltd. divides the natural stone according to the radioactive level of the building materials according to the Standard for Radionuclide Limits of Building Materials issued by the General Administration of Quality Supervision, Inspection and Quarantine. A, B, C three categories.
Among them, Class A products have the lowest level of radioactivity and can be used in any occasion. Class B products can be used in interior and exterior finishes and industrial facilities in all buildings except interior finishes. Class C standard stone can only be used on exterior finishes of buildings. â€
When consumers choose stone, they should ask the manufacturer or distributor for the radioactivity level test report of their products, and check whether the selected stone product packaging or product specification indicates the class of radioactivity level, so as to choose the right one. Stone. In home decoration, it is very safe to choose a Class A product.
Since natural stone has radioactive problems, is it safe to choose artificial stone?
In fact, artificial stone is made of clay, natural marble or granite gravel, and then cement, gypsum and unsaturated polyester resin as binder, after stirring, grinding and polishing.
The radioactive elements contained in it are not fundamentally different from natural stone. If it is artificial stone processed with high level of radioactivity, the content of radioactive elements may be higher than the radioactive element content of natural stone! If you choose artificial stone, you should also select the appropriate product category according to the selection criteria of natural stone. â€
If people are in a highly radioactive environment for a long time, it will increase the risk of cancer. When consumers purchase stone for home decoration, if there is no relevant test report, it is best to take the product sample to the testing organization, or ask the tester to go to the home to check whether the radioactivity level exceeds the standard.
Insulating glass units, or IGUs, are designed to keep homes warmer in the winter and cooler in the summer. consists of two or more glass window panes separated by a vacuum or gas-filled space to reduce heat transfer across a part of the building envelope. A window with insulating glass is commonly known as double glazing or a double-paned window, triple glazing or a triple-paned window, or quadruple glazing or a quadruple-paned window, depending upon how many panes of glass are used in its construction.
Insulated Glass can be double insulated glass, triple insulated glass, laminated insulated glass, Low-E Insulated Glass, vacuum insulated glass, insulated glass with internal blinds, Colored Insulated Glass and so on for windows, doors, exterior curtain walls, thickness, color, size can be on customer's request.
Vacuum insulated glass is a special kind of insulated glass, there is no need aluminum spacer, but 0.3mm Vacuum Spacer, more energy saving but with thinner than normal insulated glass. It can be applied to home appliance and also buildings.
